QJEEM23Chf968: JEE Main 2023 Chemistry - Class 12 JEEM23Chf968 Solution: Given below are two statements : Statement I : Ethene at 333 to …
Given below are two statements :
Statement I : Ethene at 333 to and - atm pressure in the presence of and undergoes addition polymerization to give LDP.
Statement II : Caprolactam at - in through step growth polymerizes to give Nylon 6.
In the light of the above statements, choose the correct answer from the options given below:
Multiple Choice Options
- A Both Statement I and Statement II are true
- B Statement I is true but Statement II is false
- C Statement I is false but Statement II is true
- D Both Statement I and Statement II are false
Step-by-Step Verified Solution
Statement I is false. Ethene (ethylene) under certain conditions (high pressure, high temperature) in the presence of catalysts does undergo addition polymerization, but it forms polyethylene, not LDP (Low-Density Polyethylene) specifically. The formation of low-density polyethylene (LDPE) vs high-density polyethylene (HDPE) depends on the specific conditions and catalysts used. The catalysts mentioned (AlEt3 and TiCl4) are associated with the production of HDPE through the Ziegler-Natta process, not LDPE.
Statement II is true. Caprolactam polymerizes to form Nylon 6 via a ring-opening polymerization mechanism, which is a type of step-growth polymerization. The process is often carried out at high temperatures, and water is a byproduct of the reaction, so the description in Statement II is accurate.
Therefore, Option C (Statement I is false but Statement II is true) is the correct answer.
